A logical model of spatiotemporal structures is pictured as a succession of processes in time. One usual way to formalize time structure is to assume the global existence of time points and then collect some of them to form time intervals of processes. Under this set-theoretic approach, the logic that governs the processes acquires a Boolean structure. However, in a real distributed system or a...

We consider an example of a moving closed contour and the role played by simultaneity in description light propagation on contour's sections. show that, when constrained to propagate along contour, local speed section is no longer arbitrary consistent requires conservation simultaneity.

Whereas photon coincidence spectroscopy is a promising technique for probing the nonlinear regime of cavity quantum electrodynamics in the optical domain, the accuracy is mitigated by two factors: higher–order photon correlations, which contribute to an enhanced pair count rate, and non– simultaneity of emitted photon pairs from the optical cavity. We show that the technique of photon coinciden...
